Instruction Manual - NXA-ENET8-POE+
ESD WARNING
WARNING: This product is intended to be operated ONLY from the voltages listed on the back panel or the recommended, or
included, power supply of the product. Operation from other voltages other than those indicated may cause irreversible
damage to the product and void the products warranty. The use of AC Plug Adapters is cautioned because it can allow the
product to be plugged into voltages in which the product was not designed to operate. If the product is equipped with a
detachable power cord, use only the type provided with your product or by your local distributor and/or retailer. If you are
unsure of the correct operational voltage, please contact your local distributor and/or retailer.
RACK MOUNTING
A) Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the
rack environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment in
an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer.
B) Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow required for safe
operation of the equipment is not compromised.
C) Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due
to uneven mechanical loading.
D) Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit and the effect
that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
E) Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given
to supply connections other than direct connections to the branch circuit (e.g. use of power strips)."
FCC AND CANADA EMC COMPLIANCE INFORMATION:
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and (2) this device must accept any interference received, including
interference that may cause undesired operation.
NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy, and if it is not
installed and used in accordance with the instruction manual, it may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference, in which case the user will be required
to correct the interference at his own expense.
CAN ICES-3 (A)/NMB-3(A)
To avoid ESD (Electrostatic Discharge) damage to sensitive components, make sure you are properly grounded before
touching any internal materials.
When working with any equipment manufactured with electronic devices, proper ESD grounding procedures must be
followed to make sure people, products, and tools are as free of static charges as possible. Grounding straps, conductive
smocks, and conductive work mats are specifically designed for this purpose. These items should not be manufactured
locally, since they are generally composed of highly resistive conductive materials to safely drain static discharges, without
increasing an electrocution risk in the event of an accident.
Anyone performing field maintenance on AMX equipment should use an appropriate ESD field service kit complete with at
least a dissipative work mat with a ground cord and a UL listed adjustable wrist strap with another ground cord.
WARNING: Do Not Open! Risk of Electrical Shock. Voltages in this equipment are
hazardous to life. No user-serviceable parts inside. Refer all servicing to qualified
service personnel.
Place the equipment near a main power supply outlet and make sure that you can
easily access the power breaker switch.
Avoid exposure to extreme heat and cold.

Instruction Manual - NXA-ENET8-POE+
Description of Software Features
The switch provides a wide range of advanced performance enhancing features. Flow control eliminates the loss of packets due to
bottlenecks caused by port saturation. Storm suppression prevents broadcast, multicast, and unknown unicast traffic storms from
engulfing the network. Untagged (port-based), tagged, and protocol-based VLANs, plus support for automatic GVRP VLAN
registration provide traffic security and efficient use of network bandwidth. CoS priority queueing ensures the minimum delay for
moving real-time multimedia data across the network. While multicast filtering provides support for real-time network applications.
Some of the management features are briefly described below.
Conf iguration Backup and Restore
You can save the current configuration settings to a file on the management station (using the web interface) or an TFTP server
(using the web or console interface), and later download this file to restore the switch configuration settings.
Authentication
This switch authenticates management access via the console port, Telnet, or a web browser. User names and passwords can be
configured locally or can be verified via a remote authentication server (i.e., RADIUS or TACACS+). Port-based authentication is
also supported via the IEEE 802.1X protocol. This protocol uses Extensible Authentication Protocol over LANs (EAPOL) to request
user credentials from the 802.1X client, and then uses the EAP between the switch and the authentication server to verify the
client's right to access the network via an authentication server (i.e., RADIUS or TACACS+ server).
Other authentication options include HTTPS for secure management access via the web, SSH for secure management access over
a Telnet-equivalent connection, SNMP Version 3, IP address filtering for SNMP/Telnet/web management access. MAC address
filtering and IP source guard also provide authenticated port access. While DHCP snooping is provided to prevent malicious attacks
from insecure ports.
Access Control Lists
ACLs provide packet filtering for IP frames (based on address, protocol, TCP/UDP port number or TCP control code) or any frames
(based on MAC address or Ethernet type). ACLs can be used to improve performance by blocking unnecessary network traffic or to
implement security controls by restricting access to specific network resources or protocols.
Port Configuration
You can manually configure the speed, duplex mode, and flow control used on specific ports, or use auto-negotiation to detect the
connection settings used by the attached device. Use full-duplex mode on ports whenever possible to double the throughput of
switch connections. Flow control should also be enabled to control network traffic during periods of congestion and prevent the
loss of packets when port buffer thresholds are exceeded. The switch supports flow control based on the IEEE 802.3x standard
(now incorporated in IEEE 802.3-2002).
Rate Limiting
This feature controls the maximum rate for traffic transmitted or received on an interface. Rate limiting is conf igured on interfaces
at the edge of a network to limit traffic into or out of the network. Packets that exceed the acceptable amount of traffic are
dropped.
Port Mirroring
The switch can unobtrusively mirror traffic from any port to a monitor port. You can then attach a protocol analyzer or RMON
probe to this port to perform traffic analysis and verify connection integrity.
Port Trunking
Ports can be combined into an aggregate connection. Trunks can be manually set up or dynamically configured using Link
Aggregation Control Protocol (LACP - IEEE 802.3-2005). The additional ports dramatically increase the throughput across any
connection, and provide redundancy by taking over the load if a port in the trunk should fail. The switch supports up to 8 trunks.
Storm Control
Broadcast, multicast and unknown unicast storm suppression prevents traffic from overwhelming the network.When enabled on a
port, the level of traffic passing through the port is restricted. If traffic rises above a pre-defined threshold, it will be throttled until
the level falls back beneath the threshold.
Static MAC Addresses
A static address can be assigned to a specific interface on this switch. Static addresses are bound to the assigned interface and will
not be moved. When a static address is seen on another interface, the address will be ignored and will not be written to the address
table. Static addresses can be used to provide network security by restricting access for a known host to a specific port.
IP Address Filtering
Access to insecure ports can be controlled using DHCP Snooping which filters ingress traffic based on static IP addresses and
addresses stored in the DHCP Snooping table. Traffic can also be restricted to specific source IP addresses or source IP/MAC
address pairs based on static entries or entries stored in the DHCP Snooping table.
IEEE 802.1D Bridge
The switch supports IEEE 802.1D transparent bridging. The address table facilitates data switching by learning addresses, and then
filtering or forwarding traffic based on this information. The address table supports up to 16K addresses.
Overview
20
Instruction Manual - NXA-ENET8-POE+
Store-and-Forward Switching
The switch copies each frame into its memory before forwarding them to another port. This ensures that all frames are a standard
Ethernet size and have been verified for accuracy with the cyclic redundancy check (CRC). This prevents bad frames from entering
the network and wasting bandwidth.
To avoid dropping frames on congested ports, the switch provides 12 Mbits for frame buffering. This buffer can queue packets
awaiting transmission on congested networks.
Spanning Tree Algorithm
The switch supports these spanning tree protocols:
Spanning Tree Protocol (STP, IEEE 802.1D) - This protocol provides loop detection. When there are multiple physical paths
between segments, this protocol will choose a single path and disable all others to ensure that only one route exists
between any two stations on the network. This prevents the creation of network loops. However, if the chosen path should
fail for any reason, an alternate path will be activated to maintain the connection.
Rapid Spanning Tree Protocol (RSTP, IEEE 802.1w) - This protocol reduces the convergence time for network topology
changes to about 3 to 5 seconds, compared to 30 seconds or more for the older IEEE 802.1D STP standard. It is intended
as a complete replacement for STP, but can still interoperate with switches running the older standard by automatically
reconfiguring ports to STP-compliant mode if they detect STP protocol messages from attached devices.
Multiple Spanning Tree Protocol (MSTP, IEEE 802.1s) - This protocol is a direct extension of RSTP. It can provide an
independent spanning tree for different VLANs. It simplifies network management, provides for even faster convergence
than RSTP by limiting the size of each region, and prevents VLAN members from being segmented from the rest of the
group (as sometimes occurs with IEEE 802.1D STP).
Virtual LANs
The switch supports up to 4094 VLANs. A Virtual LAN is a collection of network nodes that share the same collision domain
regardless of their physical location or connection point in the network. The switch supports tagged VLANs based on the IEEE
802.1Q standard. Members of VLAN groups can be dynamically learned via GVRP, or ports can be manually assigned to a specific
set of VLANs. This allows the switch to restrict traffic to the VLAN groups to which a user has been assigned. By segmenting your
network into VLANs, you can:
Eliminate broadcast storms which severely degrade performance in a flat network.
Simplify network management for node changes/moves by remotely configuring VLAN membership for any port, rather
than having to manually change the network connection.
Provide data security by restricting all traffic to the originating VLAN, except where a connection is explicitly defined via the
switch's routing service.
Use private VLANs to restrict traffic to pass only between data ports and the uplink ports, thereby isolating adjacent ports
within the same VLAN, and allowing you to limit the total number of VLANs that need to be configured.
Use protocol VLANs to restrict traffic to specified interfaces based on protocol type.
Traff ic Prioritization
This switch prioritizes each packet based on the required level of service, using eight priority queues with strict priority, Weighted
Round Robin (WRR) scheduling, or a combination of strict and weighted queuing. It uses IEEE 802.1p and 802.1Q tags to prioritize
incoming traffic based on input from the end-station application. These functions can be used to provide independent priorities for
delay-sensitive data and best-effort data.
This switch also supports several common methods of prioritizing layer 3/4 traffic to meet application requirements. Traffic can be
prioritized based on the priority bits in the IP frame's Type of Service (ToS) octet using DSCP, or IP Precedence. When these
services are enabled, the priorities are mapped to a Class of Service value by the switch, and the traffic then sent to the
corresponding output queue.
Quality of Service
Differentiated Services (DiffServ) provides policy-based management mechanisms used for prioritizing network resources to meet
the requirements of specific traffic types on a per-hop basis. Each packet is classified upon entry into the network based on access
lists, IP Precedence or DSCP values, or VLAN lists. Using access lists allows you select traffic based on Layer 2, Layer 3, or Layer 4
information contained in each packet. Based on network policies, different kinds of traffic can be marked for different kinds of
forwarding.
Address Resolution Protocol
The switch uses ARP to convert between IP addresses and MAC (hardware) addresses. This switch supports conventional ARP,
which locates the MAC address corresponding to a given IP address. This allows the switch to use IP addresses for routing
decisions and the corresponding MAC addresses to forward packets from one hop to the next.
Multicast Filtering
Specific multicast traffic can be assigned to its own VLAN to ensure that it does not interfere with normal network traffic and to
guarantee real-time delivery by setting the required priority level for the designated VLAN. The switch uses IGMP Snooping and
Query for IPv4,and MLD Snooping and Query for IPv6 to manage multicast group registration.
